In "ParaNorman," there's doubt among family, middle school classmates and New England towns people about just what Norman sees. Most think he simply has a vivid imagination.

Norman persists, however, and soon, he's scared up seven accusers from the grave who had sent a young girl they believed to be a witch to her doom 300 years ago in 1712.

His classmates pitch in as does the entire town with the requisite pitchforks, torches and whatever else they can lay their hands on including a bowling ball to prevent the walking dead, which now everyone can see, from taking over the town.

"ParaNorman" is filmed in stop-motion animation, whereby a character is molded out of pliable rubber and filmed frame by frame each time the figure is moved. It's a painstaking process.

The main characters in "ParaNorman" are quite adorable. The ghouls are quite scary, in a comical way.

The character voices are excellent, especially the two boys who voice the leads, Kodi Smit-Mcphee as Norman, and Tucker Albrizzi as his friend, Neil.

Anna Kendrick is the voice of Norman's sister, Courtney. Casey Affleck is the voice of another boy, Mitch. Leslie Mann is the voice of Sandra, Norman's mother. Jeff Garlin is the voice of Norman's father Perry. Elaine Stritch is the voice of Norman's Grandma. John Goodman is great as the voice of Mr. Prenderghast.

It's as if film-makers don't realize that special effects are a way to get from Point A to Point B and advance the storyline. Special effects are not necessarily an end in and of themselves. It's best to not, as happens too often in "ParaNorman," dwell on the special effects.

At one point in "ParaNorman," the screen goes entirely black. At at least two other points, the screen goes entirely white. Now that's what I call effective use of 3D imagery.

The 3D is most effective in the ghost scenes, where the apparitions trail green clouds and wisps when they move. However, "ParaNorman" doesn't have that many great 3D effects. "ParaNormam" can probably be enjoyed in the regular projection format.

Throughout, "ParaNorman" has anti-bullying as its main theme. In the final 10 minutes or so, the film gets preachy, with Norman spouting platitudes like some latter-day Cotton Mather, but with a New Age mantra.
